Pain in lambs castrated at 2 days using novel smaller and tighter rubber rings without and with local anaesthetic
(2012)Without effective pain relief, rubber ring castration of lambs is acutely painful and can also produce chronic pain. The potential of novel, smaller rubber rings to reduce this pain substantially has been investigated. Three ... -
Pain management in the neonatal piglet during routine management procedures. Part 2: Grading the quality of evidence and the strength of recommendations
(2014)Piglets reared in swine production in the USA undergo painful procedures that include castration, tail docking, teeth clipping, and identification with ear notching or tagging. These procedures are usually performed ... -
Pair-bonding and companion recognition in domestic donkeys, Equus asinus
(2013)Pair and social bonding has been documented in various taxa, where pair formations are often described as being driven by kinship or sexual motivation. However, pair-bonding between unrelated individuals where sexual ... -
Pancreatic PYY but not PPY expression is responsive to short-term nutritional state and the pancreas constitutes the major site of PYY mRNA expression in chickens
(2017)PP-fold peptides such as peptide YY (PYY) and pancreatic polypeptide (PPY) are known to play key roles in vertebrate energy homeostasis. Until recently, no gene sequence was available for avian PYY and therefore a gap ... -
The paradox of water abundance in Mato Grosso, Brazil
(2017)While much effort has gone into studying the causes and consequences of water scarcity, the concept of water abundance has received considerably less attention in academic literature. Here, we aim to address this gap by ... -
Parallel selection mapping using artificially selected mice reveals body weight control loci
(2012)Understanding how polygenic traits evolve under selection is an unsolved problem [1], because challenges exist for identifying genes underlying a complex trait and understanding how multilocus selection operates in the ... -
A parasite going from strength to strength ... or is it just a fluke?
(16/10/2014)This is a four-year research programme aiming to improve detection and control of liver fluke in cattle in the United Kingdom. It examines the disease from several perspectives and will develop a multi-faceted approach ... -
Parent age, lifespan and offspring survival: structured variation in life history in a wild population
(2010)1. Understanding the degree to which reproductive success varies with an individual’s age and lifespan, and the degree to which population-level variation mirrors individual-level variation, is central to understanding ... -
Parity effects on maternal behaviour are not related to circulating oestradiol concentrations in two breeds of sheep
(2008)Primiparous females of many species, including the sheep, do not show as competent maternal behaviour as multiparous mothers. In this study we investigated whether circulating concentrations of oestradiol might be related ...
